I Application filed February 15, 1916. Serial No. 78,478.

To all whom it may concern: 1

Be it known that 1, JOHN ANTLER, a subject of the Emperor of Germany, residing at Harrison, in the county of Kootenai and State of Idaho, have invented certain new and useful Improvements in Eraser-Hold ers for Pencils, of which. the following is a specification.

My invention relates to new and useful improvements in eraser holders, the. primary object of my invention being the provision of a novel form of holder for detachably connecting an eraser to the end of a pencil, the construction being such that the pencil may at any time be removed and a new one substituted in its place and further such that as the eraser becomes worn it may be adjusted so as to project beyond the holder until substantially worn out when the remainder may be removed and a new eraser substituted.

A still further object of my invention consists in providing a device of the above described character in which the eraser, when til in place will be held against any movement with respect to the pencil.

A still further object of my invention consists in providing an eraser holder capable of holding an eraser of much greater size than that commonly employed in connection with pencils and so shaped that in use it will prevent rolling of a pencil when placed upon an inclined surface.

With these and other objects in view, my

invention will be more fully described, illns trated in the accompanying drawings, and then specifically pointed out in the claim which is attached to and forms a part of this application.

In the drawings: I

Figure 1 is a perspective view of my improved device in use;

Fig. 2 is a fragmentary front elevational view, a portion being shown in section to illustrate certain detailsin construction;

Fig. 3 is a side elevation of the structure shown in Fig. 2;

Fig. 4: is a transverse sectional view taken on the line JL4Lof Fig. 2, looking in the direction of the arrows.

Corresponding and like parts are referred to in the followin description and indicated in all the views-o the drawings by the same reference characters. 1

Broadly speaking, my invention, the body of which is preferably formed in one piece,

includes a sleeve portion 10 adapted to re-,

ceive the unpointed terminal of a conventional pencil l1 and the head portion 12 adapted to receive and grip an eraser 13. More specifically, this body, which is preferably formed of resilient sheet metal, has the cylindrical sleeve 10 provided adjacent the head 12 with the instruck stop bead 14 which serves as an abutment to engage the end of a pencil inserted in the sleeve to limit its movement and thus prevent. its forcing the eraser outof engagement with the head. This sleeve, adjacent the bead, is provided with an opening 15 and a slot 16 extends longitudinally from this opening through the free end of the sleeve in order that the sleeve, which is resilient, may spread somewhat to receive a pencil and firmly grip the pencil when the latter is in place. Because of this arrangement, the device may be applied to pencils of slightly differing diameters or to pencils which are circular or angular in cross section. The head portion 12 includes thebase 17 and the co-acting clamping jaws l8 and 19. This head, as'a whole, is substantially rectangular in cross section, being approxlmately equal in thickness to the diameter of the pencil receiving .sleeve but of considerably greater width in order that a pencil provided with my attach- -ment laid upon an inclined surface may be prevented from rolling and in order to adapt it to receivea relatively large eraser. This head is in efiect formed of a rectangular tube provided in its wider faces with 'l|'- i shaped slots 20, the heads of which are located near the base 17 and the stems of which open through the free end of the head. By this means, the co-acting jaws 18 and 19 are formed, each jaw being substantially til-shaped in cross section with its edges spaced from the adjacent edges of the other jaw and the jaws being free for movement toward and away from each other because of the slot and the resiliency of the material of which they are formed. These jaws, adjacent their free ends, are provided with outwardly directed beads or shoulders 21 which form stops, as will be later described and in spaced relation to these beads or shoulders with out struck lugs or shoulders 22 having those faces more remote from the beads 21 beveled or inclined, as best shown in Fig. 2. The edges of the bight portions of the jaws 18 and 19 are instruck to provideopposed teeth 23 to engage in an eraser inserted in the head and the jaws are forced a into engagement with'the eraser by a' looking ring 24. This ring corresponds in cross sectional shape to the shape of the head and is proportioned to slide along the head until stopped by engagement with the beads or shoulders 21 at which time it also engages the shoulders 22 and is therefore held against accidental movement in either direction. Preferably, the outer face of this ring is corrugated or otherwise roughened, as shown, to facilitate its manipulation.

The eraser 13, as shown, is of the same cross sectional shape as the clamping head 12 and has one end squared to engage against the base of the head when in place. Pref- 4 erably, the outer end of the eraser is beveled I if it is to be employed in connection with an indelible pencil, an ink eraser may be employed instead of the ordinary pencil eraser or the holder with an ink eraser in itmay be applied to the end of a pen, if desired. As the eraser becomes worn, the ring may he slipped back and the eraser partially withdrawn from time to time and again clamped in place by replacing the ring. By this means, it is possible to wear out nearly all of the eraser before it need be replaced by another. With the jaws of the shape shown and with the clampingring clamped about the jaws near their free ends, a firm grip is maintained upon the eraser such as will hold it from movement in any direction.

Having thus described the invention, what is claimed as new is:

An attachment for pencils including a body formed at one end to provide a cylindrical pencil receiving sleeve and at its other end to provide an eraser holding head, the head portion being substantially rectangular in section and substantially equal in thickness to the diameter'of the sleeve and of considerably greater width whereby when a pencil is mounted .in the sleeve and laid upon a support it will be held against rolling movement, the walls of the head being abruptly merged into those of the sleeve to provide an enlarged seat for the inner end of an eraser mounted in the head, and means for locking an eraser in the head.

In testimony whereof I afiix my signature.
